Fatigue & Fracture Behavior in AM Materials with Nima Shamsaei of Auburn University

The ultimate goal for additive manufacturing (AM) is for those creating, building, and designing for our future to reach for AM as another tool in their toolbox as easily as they would a traditional manufacturing method. To build this trust and knowledge of industrial 3D printing, countless hours of research are necessary.  

To learn more about the research being performed at Auburn University that is shaping the future of AM, Host Fabian Alefeld speaks with a distinguished AM figure, Nima Shamsaei. Nima is a Philpott-West Point Stevens professor at Auburn University and Director of the National Center for Additive Manufacturing Excellence (NCAME). At NCAME, Nima and his team are at the forefront of research and technology and are actively studying the fracture and fatigue behavior of AM materials. In addition, a joint project with the US government and Auburn University is supporting manufacturers to create components for NASA.
